My present vinvention :comprehendsr :a novel construction and arrangement' of a wave and tide motori by the use ofwhich the energy producedibythe waves and tide can r be utilized to' douseful work. Y f It further comprehends afnovel construction of a waverm'otorwherein the paddles are constructed and mounted in a l*novel manner and are operatively `connected with l0 one direction irrespective olf whetherthe paddles are moving forwardly lor yrear- 'Ward 1fy-.. f

tion'and when moving in an opposite direc- "tion, it isineflective tofdrivefnt will be seen that the spring` l9'normally maintains the driving member 16y against a lug 24e. When theshaft l27 is moving'in its operative direction, the `gear .2l is partially rotated therebyVIA causing an .eccentric movement of the driving member lso that the walls of the slot17 Yof such vdri-vingmember will be in frictional engagement with the flange This willv causeapartial rotation of the L'shaft '10? yand since this shaft 10 is operatively connected with, the driven shaft 3 to 'drivevit,` a partial rotationof the ldriven shaft 3 willrbe effected. On thereverse movement ofthe shaft 27, which hasybeen ,driving inthe manner just described, the spring 19 will move the driven member 16 into its kconcentric.positioniwithrespect to the-shaft l0 so that no movement will be imparted'to the shaft'lO at suchtime. At this time, liowever,'tlie shaft 27 onthe opposite side is effected to cause a partial ro# tation Vof thel driven shaft 3 so that the driven shaft?)y will be continuously. revolved. Y The movement ofieach shaft 27 *is caused.j by the action of thewaveandv tide on the paddles? tfrwill Vbe, "seen that irrespective f 'offV the direction in which this action is 'exerted, the paddles will impartV movement to` theirl shafts 27.
